It doesn't require much of a grasp of the Spanish language to understand the message emblazoned across the front page of Monday's Mundo Deportivo, a popular Barcelona-based and Barca-biased daily sports newspaper.

The paper, which generally manages to capture the mood of the club's legion of fans, was desperate to avoid being paired with "Manuel Pellegrini's unstoppable" Manchester City in the draw for the last 16 of the Champions League.

Sadly for the Nou Camp club, however, Uefa's balls didn't oblige and afascinating tie lies in wait between two teams widely regarded as leading contenders for the biggest prize in European football.

The Barca media wanted to avoid City in the Champions League

The nervousness about Monday's draw illustrates a revealing change in Barcelona's mentality. A couple of years ago, they would have feared nobody - the reaction to being drawn against City, Arsenal or any other club in Europe would have been one of somewhat patronising pity towards the inevitably soon-to-be-conquered opposition.

Now, though, that unquestioning confidence has evaporated and Barca's fans will approach February's tie with respect bordering on fear.

The catalyst for the change in attitude was the Catalan club's disastrous 7-0 aggregate thrashing at the hands of Bayern Munich in last season's semi-final.

That crushing defeat, unlike previous European exits against Chelsea (in 2012)and Inter Milan (in 2010), provoked a prolonged and still ongoing process of soul-searching which has permeated to the core of the club's long-held and cherished values.

New manager Gerardo Martino is still wrestling with the problem of exactly how much he needs to change the prevailing 'tiki-taka' ideology in order to compete with a new breed of teams - most clearly embodied by Bayern but also including Manchester City - who are able to combine technical excellence with powerful athleticism.

In the last few years, since the appointment of Pep Guardiola (and to an extent under his predecessor Frank Rijkaard), Barca have proudly protected their philosophy that small can be beautiful, with under-sized players such as Xavi, Andres Iniesta and Lionel Messi able to overcome more physically imposing opponents by marrying hard work with guile and craft.

The humiliation against Bayern, however, led many observers to conclude that Barca are in need of a new injection of physicality to avoid being outmuscled by Europe's new elite. Notably, Martino has explained away his team's glaring defensive weakness against set-pieces (which will be sorely tested by the likes of Yaya Toure and Alvaro Negredo) by shrugging: "We don't have many tall players."

Carry on as before or change and adapt? It's a question that Barca are still attempting to answer, and the meeting with City will be their first major test on the European stage since those fateful losses against Bayern. It could well prove to be the tie that defines whether Martino is regarded a success at the Nou Camp.

Another fascinating sub-plot to the tie is the opportunity for City to pit their wits against the club which has enormously influenced their development in recent years as they attempt to transform themselves from unintentionally comedic underachievers to a major European superpower.
